Gnuplot.jl/ChangeLog.md

Version 1.4.1 (released on: )

• New features:

  • Implicit recipes can now returns a Vector{PlotElement};

  • Allow using single quotes in output file names (#52);

  • New function: palette_levels() can be used to modify palette levels before passing them to gnuplot;

• Bugfix:

  • Fixed BoundsErrors in hist() (#49);

  • Fixed problem when generating documentation (#51);

Version 1.4.0 (released on: May 5, 2021)

• New features:

  • Missing values are accepted if the input arrays have eltype <: AbstractFloat;

  • Missing values are also accepted in calls to hist;

  • VSCode and Pluto sessions are now properly handled (#35 and #43);

• Bugfix:

  • Multiplot were not displayed in Jupyter (#25);

  • gpvars() fails if gnuplot character encoding is utf8 (#24);

Version 1.3.0 (released on: Apr. 29, 2020)

• New features:

  • The new dgrid3d() allows to interpolate scattered 2D data on a 2D regular grid;

  • The Options structure features a new mime field containing a dictionary to map a MIME type to gnuplot terminals;

  • The Options structure features a new gpviewer field allowing to choose the display behaviour (using either gnuplot interactive terminals or anexternal viewer such as Jupyter or Juno);

  • The save() function now accepts a MIME argument in place of the term= keyword. The actual terminal is retrieved from the Options.mime dictionary;

  • The contourlines() function now accepts AbstractVector and AbstractMatrix as arguments, rather than Vector and Matrix;

  • The contourlines() function now accepts a fractions input to generate contours encompassing given fractions of the total counts in a 2D histogram;

  • The palette() function now accept a boolean smooth keyword, allowing to interpolate a discrete palette into a continuous one.

• Breaking changes:

  • The Options structure no longer provides the term_svg and term_png fields. They have been replaced by the mime dictionary.

Version 1.2.0 (released on: Apr. 20, 2020)

• New features:

  • REPL mode: a new Gnuplot.repl_init() function is available to install a gnuplot REPL;

  • Implemented the "recipe" mechanism: the recipe() function can now be extended to register new implicit recipes to display data;

  • @gp and @gsp now accepts a Gnuplot.PlotElements object, containing commands, data and plot specifications in a single argument;

  • The linetypes function now accept the lw, ps (to set the line width and point size respectively), and the dashed (to use dashed patterns in place of solid lines) keywords;

  • The new Gnuplot.options.term::String field allows to set the default terminal for interactive sessions;

  • New functions: gpvars() to retrieve all gnuplot variables, gpmargins() to retrieve current plot margins (in screen coordinates, gpranges() to retrieve current plot axis ranges;

  • New keywords accepted by @gp and @gsp: lmargin, rmargin, bmargin, tmargin, margins, to set plot margins;

  • Implemented new implicit recipes to display histograms (as returned by hist()), contour lines (as returned by contourlines()) and images;

  • Implemented automatic display of plots in both Jupyter and Juno;

  • Documentation updated;

• Breaking changes:

  • The 2D matrix are now sent to gnuplot in a column-major order, to comply with Julia array layout;

• Bugfix:

  • When a Vector{String} is passed to driver() it used to be modified, and couldn't be used again in a second call. Now the original is preserved;

  • contourlines() used to return a single blanck line to distinguish iso-contour lines, and this may cause problems in 3D plot. Now two blanck lines are returned;

Version 1.1.0 (released on: Apr. 09, 2020)

• First production ready version;
• Completed documentation and example gallery;
